Study suggests dogs with POMC are hungrier between meals and burn fewer calories when at rest

When it comes to greedy canines, labradors take the biscuit. Now researchers have shed light on why the breed is prone to a portly form.

Scientists previously revealed a mutation in a gene called POMC (proopiomelanocortin) predisposes dogs to obesity. The genetic variant is found in about a quarter of labrador retrievers and two-thirds of flat-coated retrievers, with the effect slightly larger in the former.
